The RPM Swirl offers the great control, power and high revving performance of the original Ninja RPM plus a longer skid and harder backend reaction for better pin carry. By combining the tremendously successful, patented RPM Ninja core and double shell, with Reactathane II, AMF has created a ball that will perform well on a wide range of lane conditions.
